Description:

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application is a continuation of International Patent
Application No. PCT/EP2010/054679 filed 9 Apr. 2010, which claims
priority to German Patent Application No. 10 2009 020 552.7 filed 8 May
2009, both of which are incorporated herein by reference.

[0002] The present invention relates to agents for hair treatment
containing a specific mixture of a polymer combination made up of at
least two different N-vinylpyrrolidone/N-vinylcaprolactam copolymers; use
of the agents for the temporary deformation and/or care of
keratin-containing fibers; and aerosol sprays or aerosol foams based on
those agents.

[0004] An attractive-looking hairstyle is generally regarded these days as
an indispensable element of a well-groomed appearance. Considering
fashion trends, more and more hairstyles regarded as chic are ones that,
for many types of hair, can be constructed or maintained for a longer
period of time of up to several days, using only setting ingredients.
Hair treatment agents that provide permanent or temporary shaping of the
hair therefore play an important role. Temporary shaping actions that are
intended to yield good hold without impairing the hair's healthy
appearance such as its shine can be achieved, for example, using hair
sprays, hair waxes, hair gels, hair foams, blow-dry waves, etc.

[0005] Corresponding agents for temporary shaping usually contain
synthetic polymers as a shaping component. Preparations that contain a
dissolved or dispersed polymer can be applied onto the hair by propellant
gases or by a pump mechanism. Hair gels and hair waxes in particular,
however, are generally not applied directly onto the hair but rather
distributed in the hair using a comb or the hands.

[0006] An initially important property of an agent for temporary
deformation of keratinic fibers, hereinafter also called a "styling
agent," is to impart the strongest possible hold to the treated fibers in
the shape that is generated. If the keratinic fibers involved are human
hairs, terms also used are a strong "hairstyle hold" or a high "degree of
hold" of the styling agent. Hairstyle hold is determined substantially by
the nature and quantity of the synthetic polymer used, although other
ingredients of the styling agent can also have an influence.

[0007] In addition to a high level of hold, styling agents must also meet
a large number of further requirements. These can be subdivided roughly
into hair properties; formulation properties (e.g. properties of the
foam, gel, or sprayed aerosol); and properties that relate to the
handling of the styling agent, with the properties on the hair being of
particular importance. These include moisture resistance, low tack, and a
balanced conditioning effect in particular. In addition, if possible, a
styling agent should be universally usable for all types of hair.

[0008] A plurality of synthetic polymers utilized in styling agents has
been developed to meet various requirements. The polymers can be
subdivided into cationic, anionic, nonionic, and amphoteric film-forming
and/or setting polymers. Ideally, even when a small quantity is applied
to the hair, the polymers yield a polymer film that imparts a strong hold
to the hairstyle while is sufficiently flexible not to break under
stress. If the polymer is too fragile, this results in the formation of
"film plaques" (i.e., residues that detach as the hair moves and gives
the impression that the user of the corresponding styling agent has
dandruff).

[0009] The temporarily styled hair should moreover, in addition to the
strong hairstyle hold, look healthy and natural. Hair shine plays a
dominant role here. Shine agents are therefore often added in sufficient
quantity to the hair styling agents. These shine agents include oils or
shine-imparting pigments such as mica particles. Shine-imparting
particles have the disadvantage that they detach from the hair over time
and can collect on, for example, clothing or facial skin. Oils make the
hair heavy and in some cases result in degraded adhesion of the
film-forming or setting polymers on the hair. This can result in the
constructed hairstyle not being immobilized for a sufficient period of
time by the film-forming or setting polymers (i.e., the hairstyle
collapses more quickly).

[0010] The present invention therefore attempts to make available an agent
for temporary deformation and/or care of keratinic fibers having a high
degree of hold and producing outstanding shine on the keratin-containing
fibers.

[0011] It has now been surprisingly found that this can be achieved by
combination of specific polymers.

[0012] A first subject of the invention is therefore an agent for treating
keratin-containing fibers, particularly human hair, containing in a
cosmetically acceptable carrier: [0013] i) 1.0 wt % to 2.8 wt %,

[0060] Preferred cosmetically acceptable carriers are aqueous, alcoholic,
or aqueous alcoholic media preferably having at least 10 wt % water,
based on total agent. The alcohols contained can be, in particular, lower
alcohols having 1 to 4 carbon atoms and usually used for cosmetic

hydroxyl groups is present in the agent (particularly in the presence of
at least one propellant) preferably in an amount from 40 wt % to 65 wt %,
particularly 40 wt % to 50 wt %, based on total weight of the cosmetic

polyethylene glycol and/or polypropylene glycol, based on total agent.

[0065] The agents preferably have a pH from 2 to 11. More preferably, the
pH range is from 2 to 8. References to pH here, for purposes of this
document, to pH at 25° C. unless otherwise noted.

[0066] It has proven suitable according to the present invention if the
agent optionally additionally contains at least one N--(C6 to
C20) alkylpyrrolidone. N-laurylpyrrolidone is a suitable N--(C6
to C20) alkylpyrrolidone preferred according to the present
invention.

[0067] It has been possible to increase the effects according to the
present invention by adding at least one (C2 to C6) trialkyl
citrate to the agent. It is therefore preferred if the agents
additionally contain at least one compound of formula (E)

[0069] Triethyl citrate stands out as a particularly preferred compound of
formula (E).

[0070] Agents according to the present invention contain compounds of
formula (E) preferably in an amount from 0.01 to 1 wt %, particularly
0.05 to 0.3 wt %, based on total weight of the agent.

[0071] It has been possible to achieve a similar increase in the effects

Isopropyl myristate is present in agents according to the present
invention preferably in a quantity from 0.01 to 1 wt %, particularly 0.05
to 0.3 wt %, based on total weight of the agent.

[0072] To intensify the effect according to the present invention, the
agents preferably also contain at least one surfactant. Nonionic,
anionic, cationic, and ampholytic surfactants are suitable in principle.
Ampholytic or amphoteric surfactants include zwitterionic surfactants and
ampholytes. The surfactants can already have an emulsifying effect. Use
of at least one nonionic surfactant and/or at least one cationic
surfactant is preferred in the context of this embodiment of the
invention.

[0073] The additional surfactants are present in the agent preferably in a
quantity from 0.01 wt % to 5 wt %, more preferably 0.05 wt % to 0.5 wt %,
based on total weight of the agent.

[0074] It is particularly preferred if the agents additionally contain at
least one nonionic surfactant.

[0075] Nonionic surfactants contain a hydrophilic group such as a polyol
group, a polyalkylene glycol ether group, or a combination of a polyol
and polyglycol ether group. Such compounds include: [0076] addition
products of 2 to 100 mol ethylene oxide and/or 1 to 5 mol propylene oxide
with linear and branched fatty alcohols having 8 to 30 carbon atoms, with
fatty acids having 8 to 30 carbon atoms, and with alkylphenols having 8
to 15 carbon atoms in the alkyl group, [0077] addition products,

mol ethylene oxide and/or 1 to 5 mol propylene oxide with linear and
branched fatty alcohols having 8 to 30 carbon atoms, with fatty acids
having 8 to 30 carbon atoms, and with alkylphenols having 8 to 15 carbon
atoms in the alkyl group, such as the grades obtainable under the
marketing designations Dehydrol® LS, Dehydrol® LT (Cognis),
[0078] C12 to C30 fatty acid mono- and diesters of addition
products of 1 to 30 mol ethylene oxide with glycerol, [0079] addition

with sorbitan fatty acid esters, for example, polysorbates, [0086] sugar
fatty acid esters and addition products of ethylene oxide with sugar
fatty acid esters, [0087] addition products of ethylene oxide with fatty
acid alkanolamides and fatty amines, [0088] sugar surfactants of the
alkyl and alkenyl oligoglycoside types, according to formula (T-II)

wherein R4 is an alkyl or alkenyl residue having 4 to 22 carbon
atoms, G is a sugar residue having 5 or 6 carbon atoms, and p is a number
from 1 to 10. They can be obtained by relevant methods of preparative
organic chemistry. [0089] The alkyl and alkenyl oligoglycosides can be
derived from aldoses or ketoses having 5 or 6 carbon atoms, preferably
from glucose. Preferred alkyl or alkenyl oligoglycosides are alkyl and/or
alkenyl oligoglucosides. The index number p in general formula (T-II)
indicates the degree of oligomerization (DP) (i.e., the distribution of
mono- and oligoglycosides) and is a number from 1 to 10. Whereas p in the
individual molecule must always be integral, and here can assume
especially the values p=1 to 6, the value p for a specific alkyl
oligoglycoside is an analytically ascertained calculated value that
usually represents a fractional number. Alkyl and/or alkenyl
oligoglycosides having an average degree of oligomerization p from 1.1 to
3.0 are preferably used. In terms of applications engineering, those
alkyl and/or alkenyl oligoglycosides whose degree of oligomerization is
less than 1.7, and particularly from 1.2 to 1.4, are preferred. The alkyl
or alkenyl residue R4 can be derived from primary alcohols having 4
to 11, preferably 8 to 10 carbon atoms. Typical examples are butanol,
hexanol, octanol, decanol, and undecyl alcohol as well as industrial
mixtures thereof, such as those obtained upon hydrogenation of industrial
fatty acid methyl esters or in the course of the hydrogenation of
aldehydes from Roelen oxosynthesis. Preferred are alkyl oligoglucosides
of chain length C8 to C10 (DP=1 to 3), which occur as the first
runnings upon distillational separation of industrial C8 to C18
coconut oil alcohol and can be contaminated with a proportion of less
than 6 wt % C1-2 alcohol, and alkyl oligoglucosides based on
industrial C9/11 oxoalcohols (DP=1 to 3). The alkyl or alkenyl
residue R15 can furthermore also be derived from primary alcohols
having 12 to 22, preferably 12 to 14 carbon atoms. Typical examples are
lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol,
stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol,
petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol,
erucyl alcohol, brassidyl alcohol, and industrial mixtures thereof, which
can be obtained as described above. Alkyl oligoglucosides based on
hardened C12/14 coconut alcohol having a DP of 1 to 3 are preferred.
[0090] sugar surfactants of the type of the fatty acid
N-alkylpolyhydroxyalkylamides, a nonionic surfactant of formula (T-III)

[0090] R6

##STR00008##

wherein R5CO is an aliphatic acyl residue having 6 to 22 carbon
atoms, R6 is hydrogen, an alkyl or hydroxyalkyl residue having 1 to
4 carbon atoms, and [Z] is a linear or branched polyhydroxyalkyl residue
having 3 to 12 carbon atoms and 3 to 10 hydroxyl groups. The fatty acid
N-alkylpolyhydroxyalkylamides are known substances often obtained by
reductive amination of a reducing sugar with ammonia, an alkylamine, or
an alkanolamine, and subsequent acylation with a fatty acid, a fatty acid
alkyl ester, or a fatty acid chloride. The fatty acid
N-alkylpolyhydroxyalkylamides are preferably derived from reducing sugars
having 5 or 6 carbon atoms, particularly from glucose. The preferred
fatty acid N-alkylpolyhydroxyalkylamides therefore represent fatty acid
N-alkylglucamides such as those reproduced by formula (T-IV):

[0093] For surfactants representing addition products of ethylene oxide
and/or propylene oxide with fatty alcohols or derivatives of those
addition products, both products having a "normal" homolog distribution
and those having a restricted homolog distribution can be used. A
"normal" homolog distribution is understood as mixtures of homologs
obtained upon reaction of fatty alcohol and alkylene oxide using alkali
metals, alkali metal hydroxides, or alkali metal alcoholates as
catalysts. Restricted homolog distributions are obtained when, for
example, hydrotalcites, alkaline-earth metal salts of ethercarboxylic
acids, or alkaline-earth metal oxides, hydroxides, or alcoholates are
used as catalysts. Use of products having a restricted homolog
distribution can be preferred.

[0094] Very particularly preferably, agents according to the present
invention contain as a surfactant at least one addition product of 15 to
100 mol ethylene oxide, particularly 15 to 50 mol ethylene oxide, with a
linear or branched (particularly linear) fatty alcohol having 8 to 22
carbon atoms. This includes ceteareth-15, ceteareth-25, or ceteareth-50,
marketed as Eumulgin® CS 15 (Cognis), Cremophor A25 (BASF SE), or
Eumulgin® CS 50 (Cognis).

[0095] All anionic surface-active substances suitable for use on the human
body are, in principle, appropriate as anionic surfactants. These have an
anionic group imparting water solubility, for example a carboxylate,
sulfate, sulfonate, or phosphate group, and a lipophilic alkyl group
having approximately 8 to 30 carbon atoms. Glycol ether or polyglycol
ether groups, ester, ether, and amide groups, and hydroxyl groups can
additionally be contained in the molecule. Examples of suitable anionic
surfactants are, each in the form of the sodium, potassium, and ammonium
and mono-, di, and trialkanolammonium salts having 2 to 4 carbon atoms in
the alkanol group: [0096] linear and branched fatty acids having 8 to

carbon atoms and 1 to 6 double bonds; [0109] esters of tartaric acid and
citric acid with alcohols, representing addition products of
approximately 2 to 15 molecules of ethylene oxide and/or propylene oxide
with fatty alcohols having 8 to 22 carbon atoms; [0110] alkyl and/or

and tallow fatty acid monoglyceride, as well as their ethylene oxide
adducts with sulfur trioxide or chlorosulfonic acid in the form of their
sodium salts. It is preferable to use monoglyceride sulfates of formula
(T-VII) wherein R8CO is a linear acyl residue having 8 to 18 carbon
atoms, [0116] amide ethercarboxylic acids; [0117] condensation products
of C8 to C30 fatty alcohols with protein hydrolysates and/or
amino acids and derivatives thereof, known to one skilled in the art as
protein fatty acid condensates, such as Lamepon® grades, Gluadin®
grades, Hostapon® KCG, or the Amisoft® grades.

[0118] Preferred anionic surfactants are alkyl sulfates, alkyl polyglycol
ether sulfates, and ethercarboxylic acids having 10 to 18 carbon atoms in
the alkyl group and up to 12 glycol ether groups in the molecule,
sulfosuccinic acid mono- and dialkyl esters having 8 to 18 carbon atoms
in the alkyl group, and sulfosuccinic acid monoalkylpolyoxyethyl esters
having 8 to 18 carbon atoms in the alkyl group and 1 to 6 oxyethyl
groups, monoglycerol disulfates, alkyl and alkenyl ether phosphates, and
protein fatty acid condensates.

[0119] Cationic surfactants of the quaternary ammonium compound,
esterquat, and amidoamine types are furthermore usable according to the
present invention. Preferred quaternary ammonium compounds are ammonium
halides, particularly chlorides and bromides such as
alkyltrimethylammonium chlorides, dialkyldimethylammonium chlorides, and
trialkylmethylammonium chlorides. The long alkyl chains of these
surfactants preferably comprise 10 to 18 carbon atoms, as in
cetyltrimethylammonium chloride, stearyltrimethylammonium chloride,
distearyldimethylammonium chloride, lauryldimethylammonium chloride,
lauryldimethylbenzylammonium chloride, and tricetylmethylammonium
chloride. Further preferred cationic surfactants are the imidazolium
compounds having the INCI designations Quaternium-27 and Quaternium-83.

[0120] "Zwitterionic surfactants" refers to those surface-active compounds
having at least one quaternary ammonium group and at least one
--COO.sup.(-) or SO3.sup.(-) group. Particularly suitable
zwitterionic surfactants are betaines such as
N-alkyl-N,N-dimethylammonium glycinates, for example,
cocalkyldimethylammonium glycinate,
N-acylaminopropyl-N,N-dimethylammonium glycinates, for example,
cocacylaminopropyldimethylammonium glycinate, and
2-alkyl-3-carboxymethyl-3-hydroxyethylimidazolines, each having 8 to 18
carbon atoms in the alkyl or acyl group, as well as
cocacylaminoethylhydroxyethylcarboxymethyl glycinate. A preferred
zwitterionic surfactant is the fatty acid amide derivative known by the
INCI name Cocamidopropyl Betaine.

[0121] "Ampholytes" refer to those surface-active compounds having in the
molecule, in addition to a C8 to C24 alkyl or acyl group, at
least one free amino group and at least one --COOH or --SO3H group
and are capable of forming internal salts. Examples of suitable
ampholytes are N-alkylglycines, N-alkylpropionic acids,
N-alkylaminobutyric acids, N-alkyliminodipropionic acids,
N-hydroxyethyl-N-alkylamidopropylglycines, N-alkyltaurines,
N-alkylsarcosines, 2-alkylaminopropionic acids, and alkylaminoacetic
acids, each having approximately 8 to 24 carbon atoms in the alkyl group.
Particularly preferred ampholytes are N-cocalkylaminopropionate,
cocacylaminoethylaminopropionate, and C12-18 acyl sarcosine.

[0122] Agents according to the present invention can optionally
additionally contain at least one film-forming polymer and/or setting
polymer. These additional polymers are different from copolymer (a) and
copolymer (b). The optionally added film-forming and/or setting polymers
are preferably cationic and/or nonionic.

[0123] "Film-forming polymers" refer to those polymers that, upon drying,
leave behind a continuous film on the skin, hair or nails. Film-formers
of this kind can be used in a very wide variety of cosmetic products such
as face masks, make-up, hair setting agents, hair sprays, hair gels, hair
waxes, hair therapies, shampoos, or nail polishes. Particularly preferred
are those polymers having sufficient solubility in alcohol or in
water/alcohol mixtures so as to be present in completely dissolved form
in the agent. The film-forming polymers can be of synthetic or natural
origin.

[0124] "Film-forming polymers" further include those polymers that, when
applied in a 0.01 to 20-wt % aqueous, alcoholic, or aqueous alcoholic
solution, are capable of depositing a transparent polymer film on the
hair.

[0125] Setting polymers contribute to hold and/or to building up hair
volume and hair fullness of the overall hairstyle. These polymers are
also film-forming polymers and are therefore generally typical substances
for shape-imparting hair-treatment agents such as hair setting agents,
hair foams, hair waxes, hair sprays. It is certainly possible for film
formation to be localized, and for only a few fibers to be connected to
one another.

[0126] The "curl retention" test is often used as a test method for the
setting effect of a polymer.

[0127] In addition, the agent according to the present invention can
contain at least one cationic film-forming and/or cationic setting
polymer.

[0128] The additional cationic film-forming and/or cationic setting
polymers comprise at least one structural unit having at least one
permanently cationized nitrogen atom. "Permanently" cationized nitrogen
atoms are to be understood as those nitrogen atoms having a positive
charge and thereby form a quaternary ammonium compound. Quaternary
ammonium compounds are usually produced by reaction of tertiary amines
with alkylating agents such as methyl chloride, benzyl chloride, dimethyl
sulfate, dodecyl bromide, as well as ethylene oxide. Depending on the
tertiary amine used, the following groups are particularly known:
alkylammonium compounds, alkenylammonium compounds, imidazolinium
compounds, and pyridinium compounds.

[0129] Preferred agents for this embodiment contain the cationic
film-forming and/or cationic setting polymers in an amount from 0.1 wt %
to 20.0 wt %, preferably 0.2 wt % to 10.0 wt %, more preferably from 0.5
wt % to 5.0 wt %, based on total weight of the agent.

[0131] Those cationic quaternized celluloses having more than one
permanent cationic charge in a side chain are generally advantageous for
purposes of the embodiment.

[0132] To be emphasized among the cationic cellulose derivatives are those
that are manufactured from a reaction of hydroxyethyl cellulose with a
dimethyldiallylammonium reagent (in particular dimethyldiallylammonium
chloride), if applicable in the presence of further reagents. Among these
cationic celluloses, those cationic celluloses having the INCI name
Polyquaternium-4 and marketed, for example, under the designations
Celquat® H 100, Celquat® L 200 by the National Starch company,
are particularly suitable.

[0133] Also suitable are those cationic film-forming and/or cationic
setting polymers having at least one structural unit of formula (I) and
at least one structural unit of formula (VI) and, if applicable, at least
one structural unit of formula (V),

or a methyl group, A1 and A2, mutually independently, are an
ethane-1,2-diyl, propane-1,3-diyl, or butane-1,4-diyl group, R2,
R3, R5, and R6, mutually independently, are a (C1 to
C4) alkyl group, and R7 is a (C8 to C30) alkyl group.

[0135] Suitable compounds include those obtainable commercially as
[0136] copolymers of dimethylaminoethyl methacrylate, quaternized with
diethyl sulfate, with vinylpyrrolidone, having the INCI name

(BASF SE), [0137] copolymers of
methacryloylaminopropyllauryldimethylammonium chloride with
vinylpyrrolidone and dimethylaminopropyl methacrylamide, having the INCI
name Polyquaternium-55, under the commercial names Styleze® W-10,
Styleze® W-20 (ISP company).

[0138] Also serving as film-forming and/or setting polymers usable
particularly preferably for purposes of the embodiment, selected from
cationic polymers having at least one structural unit comprising a
permanently cationized nitrogen atom are those cationic film-forming
and/or cationic setting copolymers having at least one structural element
of formula (M1)

##STR00012##

group, and additionally comprise at least one further cationic and/or
nonionic structural element.

[0139] The statements made above apply with regard to compensation for the
positive polymer charge.

[0140] It is preferred in turn according to the present invention in the
context of this embodiment if the cationic film-forming and/or cationic
setting polymer according to the present invention contains at least one
copolymer (c1) that, alongside a structural element of formula (M1),
additionally encompasses a structural element of formula (I)

[0143] It is particularly preferred in this context if copolymers (c1)
contain, alongside polymer units resulting from incorporation of the
aforesaid structural units according to formulas (M1) and (I) into the
copolymer, a maximum of 5 wt %, preferably a maximum of 1 wt % of polymer

(c1) are preferably constructed exclusively from structural units of
formula (M1) where R''=methyl and (I), and can be described by the
general formula (Poly1)

##STR00014##

where m and p each vary depending on the molecular weight of the polymer
and are not intended to signify that these are block copolymers.
Structural units of formula (M1) and formula (I) can instead be present
in statistically distributed fashion in the molecule.

[0144] If a chloride ion is used to compensate for the positive charge of
the polymer of formula (Poly1), these
N-methylvinylimidazole/vinylpyrrolidone copolymers are then referred to
as Polyquaternium-16 according to INCI nomenclature, and are obtainable,
for example, from BASF under the trade names Luviquat® Style,
Luviquat® FC 370, Luviquat® FC 550, Luviquat® FC 905, and
Luviquat® HM 552.

[0145] If a methosulfate is used to compensate for the positive charge of
the polymer of formula (Poly1), these
N-methylvinylimidazole/vinylpyrrolidone copolymers are then referred to
as Polyquaternium-44 according to INCI nomenclature, and are obtainable,
for example, from BASF under the trade names Luviquat® UltraCare.

[0146] Particularly preferred agents of this embodiment contain a

molecular weight from 50 to 400 kDa, preferably from 100 to 300 kDa, more
preferably from 150 to 250 kDa, and in particular from 190 to 210 kDa,

the present invention can also contain copolymers (c2) that, proceeding
from copolymer (c1), contain structural units of formula (II) as
additional structural units:

##STR00015##

[0148] Further particularly preferred agents according to the present
invention of this embodiment contain, as a cationic film-forming and/or
cationic setting polymer, at least one copolymer (c2) having at least one
structural unit according to formula (M1-a), at least one structural unit

##STR00016##

[0149] Here it is particularly preferred in this embodiment if copolymers

aforesaid structural units according to formulae (M1-a), (I), and (II)
into the copolymer, a maximum of 5 wt %, preferably a maximum of 1 wt %
of polymer units based on the incorporation of other monomers. Copolymers
(c2) are preferably constructed exclusively from structural units of
formulas (M1-a), (I), and (II), and can be described by the general
formula (Poly2)

##STR00017##

where m, n and p each vary depending on the molecular weight of the
polymer and are not intended to signify that these are block copolymers.
Structural units of the aforesaid formulae can instead be present in
statistically distributed fashion in the molecule.

[0151] If a methosulfate is used to compensate for the positive charge of
the polymer of formula (Poly2), these
N-methylvinylimidazole/vinylpyrrolidone/vinylcaprolactam copolymers are
then referred to as Polyquaternium-46 according to INCI nomenclature, and
are obtainable, for example, from BASF under the trade name Luviquat®
Hold.

[0153] Particularly preferred agents of this embodiment contain a
copolymer (c2) having molecular weights within a specific range. Agents
according to the present invention in which copolymer (c2) has a
molecular weight from 100 to 1000 kDa, preferably from 250 to 900 kDa,
more preferably from 500 to 850 kDa, and in particular from 650 to 710
kDa, are preferred.

[0154] In addition to or instead of copolymer(s) (c1) and/or (c2), the
agents can also contain, as a cationic film-forming and/or cationic
setting polymer, copolymers (c3) having as structural units structural
units of formulas (M1-a) and (I), as well as further structural units
from the group of the vinylimidazole units and further structural units
from the group of the acrylamide and/or methacrylamide units.

[0155] Further particularly preferred agents of this embodiment contain,
as an additional cationic film-forming and/or cationic setting polymer,
at least one copolymer (c3) having at least one structural unit according
to formula (M-1a), at least one further structural unit according to
formula (I), at least one further structural unit according to formula
(VII), and at least one further structural unit according to formula

##STR00018##

[0156] Here it is particularly preferred in the context of this embodiment
if copolymers (c3) contain, in addition to polymer units resulting from
incorporation of the aforesaid structural units according to formulas
(M1-a), (I), (VII), and (VIII) into the copolymer, a maximum of 5 wt %,
preferably a maximum of 1 wt %, of polymer units based on the
incorporation of other monomers. Copolymers (c3) are preferably
constructed exclusively from structural units of formulas (M 1-a), (I),
(VII), and (VIII) and can be described by the general formula (Poly3)

##STR00019##

wherein m, n, o and p each vary depending on the molecular weight of the
polymer and are not intended to signify that these are block copolymers.
Structural units of formulas (M1-a), (I), (VII), and (VIII) can instead
be present in statistically distributed fashion in the molecule.

[0158] If a methosulfate is used to compensate for the positive charge of
the polymer of formula (Poly3), these
N-methylvinylimidazole/vinylpyrrolidone/vinylimidazole/methacrylamide
copolymers are referred to as Polyquaternium-68 according to INCI
nomenclature, and are obtainable, for example, from BASF under the trade
name Luviquat® Supreme.

[0160] Particularly preferred agents of this embodiment contain a
copolymer (c3) having molecular weights within a specific range. Agents
according to the present invention in which copolymer (c3) has a
molecular weight from 100 to 500 kDa, preferably from 150 to 400 kDa,
more preferably from 250 to 350 kDa, and in particular from 290 to 310
kDa, are preferred here.

[0161] Among the additional cationic film-forming and/or setting polymers
chosen from the cationic polymers having at least one structural element
of the above formula (M1), those considered preferred are:

[0162] vinylpyrrolidone/1-vinyl-3-methyl-1H-imidazolium chloride
copolymers (such as the one having the INCI name Polyquaternium-16 under
the commercial designations Luviquat® Style, Luviquat® FC 370,
Luviquat® FC 550, Luviquat® FC 905, and Luviquat® HM 552
(BASF SE)), [0163] vinylpyrrolidone/1-vinyl-3-methyl-1H-imidazolium
methyl sulfate copolymers (such as the one having the INCI name
Polyquaternium-44 under the commercial designations Luviquat® Care
(BASF SE)), [0164]
vinylpyrrolidone/vinylcaprolactam/1-vinyl-3-methyl-1H-imidazolium
terpolymers (such as the one having the INCI name Polyquaternium-46 under
the commercial designations Luviquat® Care or Luviquat® Hold
(BASF SE)), [0165]

(BASF SE)), as well as mixtures of said polymers.

[0166] Agents according to the present invention can contain, as an
additional film-forming and/or setting polymer, at least one nonionic
film-forming and/or nonionic setting polymer. A "nonionic polymer" refers
to a polymer that, in a protic solvent under standard conditions, carries
substantially no structural units having permanently cationic or anionic
groups that must be compensated for by counterions in order to obtain
electroneutrality. "Cationic" groups include, for example, quaternized
ammonium groups but not protonated amines. "Anionic" groups include, for
example, carboxyl and sulfonic-acid groups.

[0167] The nonionic film-forming and/or nonionic setting polymers are
present in the agent of this embodiment preferably in an amount from 0.1
wt % to 20.0 wt %, more preferably from 0.2 wt % to 15.0 wt %, very
particularly preferably from 0.5 wt % to 10.0 wt %, based on total weight
of the agent according to the present invention.

that carry, according to formula (M2), a hydrogen atom, an acetyl group,
or a propanoyl group, particularly an acetyl group, as R', are
particularly suitable according to the present invention.

[0169] Nonionic film-forming and/or nonionic setting polymers are
preferably chosen from at least one polymer of

[0170] homopolymers and nonionic copolymers of N-vinylpyrrolidone,

[0171] nonionic copolymers of isobutene.

[0172] Suitable polyvinylpyrrolidones include commercial products such as
Luviskol® K 90 or Luviskol® K 85 of the BASF SE Company.

[0173] Suitable polyvinyl alcohols are marketed, for example, under the
commercial designations Elvanol® by Du Pont, or Vinol® 523/540 by
the Air Products Company.

[0174] Suitable polyvinyl acetate is marketed, for example, as an emulsion
under the trade name Vinac® by the Air Products Company.

[0175] Agents having as a nonionic film-forming and/or nonionic setting
polymer at least one polymer chosen from [0176] polyvinylpyrrolidone,
[0177] copolymers of N-vinylpyrrolidone and vinyl esters of carboxylic
acids having 2 to 18 carbon atoms, particularly of N-vinylpyrrolidone and
vinyl acetate, [0178] copolymers of N-vinylpyrrolidone and
N-vinylimidazole and methacrylamide, [0179] copolymers of
N-vinylpyrrolidone and N-vinylimidazole and acrylamide, [0180] copolymers
of N-vinylpyrrolidone with N,N-di(C1 to C4) alkylamino-(C2
to C4) alkylacrylamide, are very particularly preferred according to
the present invention.

[0181] Further preferred agents of this embodiment contain, as a nonionic
film-forming and/or nonionic setting polymer, at least one copolymer (c4)
having at least one further structural unit according to formula (I) and
at least one structural unit according to formula (VII) and at least one
structural unit according to formula (VIII)

##STR00021##

[0182] Here it is particularly preferred that these copolymers contain, in
addition to polymer units resulting from incorporation of the aforesaid
structural units according to formulas (I), (VII), and (VIII) into the
copolymer, a maximum of 5 wt %, preferably a maximum of 1 wt % of polymer
units based on incorporation of other monomers. Copolymers (c4) are
preferably constructed exclusively from structural units of formulae (I),
(VII), and (VIII) and can be described by the general formula (Poly4)

##STR00022##

where m, n, o and p each vary depending on the molecular weight of the
polymer and are not intended to signify that these are block copolymers.
Structural units of formulae (I), (VII), and (VIII) can instead be
present in statistically distributed fashion in the molecule.

[0183] A particularly preferred polymer is selected in this context from
polymers having the INCI name VP/Methacrylamide/Vinyl Imidazole
Copolymer, obtainable, for example, under the trade name Luviset Clear
from the BASF SE Company.

[0184] Agents according to the present invention can contain organic
solvents or a mixture of solvents having a boiling point under
400° C. as additional co-solvents in an amount from 0.1 to 15 wt
%, preferably 1 to 10 wt %, based on total agent. Unbranched or branched
hydrocarbons such as pentane, hexane, isopentane, and cyclic hydrocarbons
such as cyclopentane and cyclohexane, are particularly suitable as
additional co-solvents. Further particularly preferred water-soluble
solvents are glycerol, ethylene glycol, butylene glycol, and propylene
glycol, in an amount of up to 30 wt % based on total agent.

[0185] In particular, the addition of glycerol and/or propylene glycol
and/or polyethylene glycol and/or polypropylene glycol increases the
flexibility of the polymer film formed upon utilization of the agent
according to the present invention. If a flexible hold is desired, the
agents therefore contain preferably 0.01 to 30 wt % glycerol and/or
propylene glycol and/or polyethylene glycol and/or polypropylene glycol,
based on total agent.

[0186] The agents preferably have a pH from 2 to 11. Particularly
preferably, the pH range is from 2 to 8. Reference to pH, for purposes of
this document, refers to pH at 25° C. unless otherwise noted.

[0187] Agents according to the present invention can furthermore contain
adjuvants and additives typically added to conventional styling agents.

[0188] Care-providing substances may be mentioned in particular as
suitable adjuvants and additives.

[0189] The agent can contain as a care-providing substance, for example,
at least one protein hydrolysate and/or a derivative thereof.

[0190] Protein hydrolysates are product mixtures obtained by acid-, base-,
or enzyme-catalyzed breakdown of proteins. The term "protein
hydrolysates" according to the present invention refers to total
hydrolysates as well as individual amino acids and derivatives thereof,
as well as mixtures of different amino acids. Polymers constructed from
amino acids and amino-acid derivatives are also understood according to
the present invention under the term "protein hydrolysates". Included
among the latter are, for example, polyalanine, polyasparagine,
polyserine, etc. Further examples of compounds usable according to the
present invention are L-alanyl-L-proline, polyglycine,
glycyl-L-glutamine, or D/L-methionine-S-methylsulfonium chloride.
β-Amino acids and their derivatives, such as β-alanine,
anthranilic acid, or hippuric acid, can of course also be used according
to the present invention. The molecular weight of protein hydrolysates
usable according to the present invention is from 75 (the molecular
weight of glycine) to 200,000; the molecular weight is preferably 75 to
50,000 Dalton, and very particularly preferably 75 to 20,000 Dalton.

[0191] According to the present invention, protein hydrolysates of both
vegetable and animal origin, or of marine or synthetic origin, can be
used.

[0192] Animal protein hydrolysates include hydrolysates of elastin,
collagen, keratin, silk, and milk protein, which can also be present in
the form of salts. Such products are marketed, for example, under the
trademarks Dehylan® (Cognis), Promois® (Interorgana),
Collapuron® (Cognis), Nutrilan® (Cognis), Gelita-Sol®
(Deutsche Gelatine Fabriken Stoess & Co), Lexein® (Inolex), and
Kerasol® (Croda).

[0193] Use of silk protein hydrolysates is of particular interest. "Silk"
is understood as the fibers of the cocoon of the mulberry silkworm
(Bombyx mori L.). The raw silk fiber is made up of a double thread of
fibroin. Sericin serves as a glue substance holding this double thread
together. Silk is made up of 70 to 80 wt % fibroin, 19 to 28 wt %
sericin, 0.5 to 1 wt % fat, and 0.5 to 1 wt % coloring agents and mineral
constituents.

[0195] Water-insoluble fibroin is included among the scleroproteins having
a long-chain molecular structure. The principal constituents of fibroin
are glycine (44 wt %), alanine (26 wt %), and tyrosine (13 wt %). A
further essential structural feature of fibroin is the hexapeptide
sequence Ser-Gly-Ala-Gly-Ala-Gly.

[0196] It is technically simple to separate the two silk proteins from one
another. It is therefore not surprising that both sericin and fibroin are
known, each individually, as raw materials for use in cosmetic products.
Protein hydrolysates and protein derivatives based on the respective
individual silk proteins are also known raw materials in cosmetic agents.
For example, sericin as such is marketed by Pentapharm Ltd. as a
commercial product with the designation Sericin Code 303-02. Fibroin is
offered far more frequently on the market as a protein hydrolysate, at
various molecular weights. These hydrolysates are marketed in particular
as "silk hydrolysates."Hydrolyzed fibroin having average molecular
weights from 350 to 1000 is marketed, for example, under the commercial
designation Promois® Silk.

[0197] The positive properties of the silk protein derivatives from
sericin and fibroin, individually for each one, are known in the
literature. For example, the sales brochure of the Pentapharm Company
describes the cosmetic effects of sericin on the skin as
irritation-soothing, hydrating, and film-forming. The effect of a fibroin
derivative is described, for example in DE 31 39 438 A1, as providing
care to and revival of the hair. According to DE 102 40 757 A1, with the
simultaneous use of sericin and fibroin, or derivatives and/or
hydrolysates thereof, it is furthermore possible to achieve a synergistic
enhancement of the positive effects of the silk proteins and their
derivatives.

[0198] It is therefore preferred to use in the agent as a silk protein
hydrolysate, an active-substance complex (A) made up of the active
substance (A1) chosen from sericin, sericin hydrolysates, and/or
derivatives thereof, as well as mixtures thereof, and an active substance
(A2) chosen from fibroin and/or fibroin hydrolysates and/or derivatives
thereof and/or mixtures thereof.

[0199] The active-substance complex (A) significantly improves, in
synergistic fashion, the essential internal and external structural
features presented above, as well as the strength and elasticity of human
hairs.

[0200] Particularly good care-providing properties can be achieved if one
of the two active-substance components of the active-substance complex
(A) is used in the natural or, if need be, solubilized form. It is also
possible to utilize a mixture of several active substances (A1) and/or
(A2).

[0201] It can be preferred for the two active substances (A1) and (A2) to
be used in the agents according to the present invention at a ratio from
10:90 to 70:30, particularly 15:85 to 50:50, and very particularly 20:80
to 40:60, based on their respective active-substance contents.

[0203] Although use of protein hydrolysates as such is preferred, it is
also optionally possible to use instead of them, if applicable,
amino-acid mixtures obtained in different fashion. It is likewise
possible to use derivatives of protein hydrolysates, for example, in the
form of their fatty acid condensation products. Such products are
marketed, for example, under the designations Lamepon® (Cognis),
Lexein® (Inolex), Crolastin® (Croda), Crosilk® (Croda), or
Crotein® (Croda).

[0204] The teaching according to the present invention of course
encompasses all isomeric forms, such as cis-trans isomers, diastereomers,
and chiral isomers. It is also possible according to the present
invention to use a mixture of several protein hydrolysates.

[0205] Protein hydrolysates can be present in the agents, for example, in
concentrations from 0.01 wt % to 20 wt %, preferably 0.05 wt % to 15 wt
%, and very particularly preferably from 0.05 wt % to 5 wt %, based on
total application preparation.

[0206] The agent according to the present invention can further contain at
least one vitamin, provitamin, vitamin precursor, and/or derivatives
thereof as a care-providing substance.

[0207] Those vitamins, provitamins, and vitamin precursors that are
usually assigned to groups A, B, C, E, F, and H are preferred according
to the present invention.

[0208] The group of substances referred to as vitamin A includes retinol
(vitamin A1) as well as 3,4-didehydroretinol (vitamin A2).
β-Carotene is the provitamin of retinol. Vitamin A components that
are suitable according to the present invention are, for example, vitamin
A acid and its esters, vitamin A aldehyde, and vitamin A alcohol, as well
as its esters thereof such as the palmitate and acetate. The agents
contain the vitamin A component preferably in quantities from 0.05 to 1
wt % based on the entire application preparation.

[0209] Members of the vitamin B group or vitamin B complex include, among
others: [0210] Vitamin B1 (thiamine) [0211] Vitamin B2
(riboflavin) [0212] Vitamin B3. The compounds nicotinic acid and
nicotinic acid amide (niacinamide) are often listed under this
designation. Nicotinic acid amide is preferred according to the present
invention; it is contained in the agents according to the present
invention preferably in quantities from 0.05 to 1 wt % based on total
application preparation. [0213] Vitamin B5 (pantothenic acid,
panthenol, and pantolactone). Panthenol and/or pantolactone are
preferably used in the context of this group. Derivatives of panthenol
usable according to the present invention are, in particular, the esters
and ethers of panthenol as well as cationically derivatized panthenols.
Individual representatives are, for example, panthenol triacetate,
panthenol monoethyl ether and the monoacetate thereof, and cationic
panthenol derivatives. The aforesaid compounds of the vitamin B5
type are contained in the agents according to the present invention
preferably in quantities from 0.05 to 10 wt % based on total application
preparation. Quantities from 0.1 to 5 wt % are particularly preferred.
[0214] Vitamin B6 (pyridoxine as well as pyridoxamine and
pyridoxal). The aforesaid compounds of the vitamin B6 type are
contained in the agents according to the present invention preferably in
quantities from 0.01 to 5 wt % based on the entire application
preparation. Quantities from 0.05 to 1 wt % are particularly preferred.

[0215] Vitamin C (ascorbic acid). Vitamin C is utilized in the agents
according to the present invention preferably in quantities from 0.1 to 3
wt % based on the entire application preparation. Utilization in the form
of the palmitic acid ester, the glucosides or phosphates can be
preferred. Utilization in combination with tocopherols can likewise be
preferred.

[0216] Vitamin E (tocopherols, in particular α-tocopherol).
Tocopherol and its derivatives, which include in particular the esters
such as the acetate, nicotinate, phosphate, and succinate, are contained
in the agents according to the present invention preferably in quantities
from 0.05 to 1 wt % based on the entire application preparation.

[0217] Vitamin F. The term "vitamin F" is usually understood as essential
fatty acids, in particular linoleic acid, linolenic acid, and arachidonic
acid.

[0218] Vitamin H. This refers to
(3aS,4S,6aR)-2-oxohexahydrothienol[3,4-d]-imidazole-4-valeric acid, for
which the trivial name "biotin" has nevertheless since become
established. Biotin is contained in the agents according to the present
invention preferably in quantities from 0.0001 to 1.0 wt %, particularly
from 0.001 to 0.01 wt %, based on total application preparation.

[0220] Panthenol, pantolactone, pyridoxine and its derivatives, as well as
nicotinic acid amide and biotin, are particularly preferred.

[0221] D-panthenol is used very particularly preferably as a
care-providing substance, if applicable in combination with at least one
of the aforesaid silicone derivatives.

[0222] Like the addition of glycerol and/or propylene glycol, the addition
of panthenol also increases the flexibility of the polymer film formed
upon utilization of the agent according to the present invention. If a
particularly flexible hold is desired, agents according to the present
invention can thus contain panthenol instead of or in addition to
glycerol and/or propylene glycol. In a preferred embodiment the agents
contain panthenol, preferably in an amount from 0.05 to 10 wt %, more
preferably 0.1 to 5 wt %, based on total agent.

[0223] Agents according to the present invention can further contain at
least one plant extract as a care-providing substance.

[0224] These extracts are usually produced by extraction of the entire
plant. In individual cases, however, it may also be preferred to produce
the extracts exclusively from blossoms and/or leaves of the plant.

[0225] Regarding plant extracts usable according to the present invention,
reference is made to extracts listed in the table beginning on page 44 of
the 3rd edition of the "Guideline for declaring the contents of cosmetic
agents" [Leitfaden zur Inhaltsstoffdeklaration kosmetischer Mittel]
published by the Association of the personal hygiene and washing agents
industry [Industrieverband Korperpflege- and Waschmittel e.V. (IKW)],
Frankfurt.

[0229] Water, alcohols, and mixtures thereof can be used as extraction
agents for manufacturing the aforesaid plant extracts. Among the
alcohols, lower alcohols such as ethanol and isopropanol, particularly
polyvalent alcohols such as ethylene glycol and propylene glycol, both as
the only extraction agent and mixed with water, are preferred. Plant
extracts based on water/propylene glycol at a ratio from 1:10 to 10:1
have proven particularly suitable. It is possible according to the
present invention to use hydrous plant extracts in the context of the
predefined water quantity. This is not, however, preferred according to
the present invention.

[0230] According to the present invention, plant extracts can be used in
both pure and diluted form. If they are used in diluted form, they
usually contain approximately 2 to 80 wt % active substance, and contain
as a solvent the extraction agent or extraction agent mixture used to
obtain them.

[0231] It may furthermore be preferred to use mixtures of several,
particularly two, different plant extracts in the agents.

[0232] Agents according to the present invention contain these
care-providing substances preferably in amounts from 0.001 to 2 wt %,
particularly 0.01 to 0.5 wt %, based on total application preparation.

[0233] Mono- or oligosaccharides can also be used as a care-providing
substance in agents according to the present invention.

[0234] Both monosaccharides and oligosaccharides, for example, raw sugar,
milk sugar, and raffinose, can be used. Use of monosaccharides is
preferred. Among the monosaccharides, those compounds containing 5 or 6
carbon atoms are preferred.

[0235] Suitable pentoses and hexoses include ribose, arabinose, xylose,
lyxose, allose, altrose, glucose, mannose, gulose, idose, galactose,
talose, fucose and fructose. Arabinose, glucose, galactose and fructose
are carbohydrates that are preferably used; it is very particularly
preferred to use glucose, which is suitable both in the D-(+) or L-(-)
configuration or as a racemate.

[0236] Derivatives of these pentoses and hexoses, such as the
corresponding -onic and -uronic acids (sugar acids), sugar alcohols, and
glycosides, can also be used according to the present invention.
Preferred sugar acids are gluconic acid, glucuronic acid, saccharic acid,
mannosaccharic acid, and mucic acid. Preferred sugar alcohols are
sorbitol, mannitol, and dulcitol. Preferred glycosides are the
methylglucosides.

[0237] Because the mono- or oligosaccharides that are used are usually
obtained from natural raw materials such as starch, they typically
exhibit the configurations corresponding to those raw materials (e.g.,
D-glucose, D-fructose and D-galactose).

[0238] The mono- or oligosaccharides are present in agents according to
the present invention preferably in an amount from 0.1 to 8 wt %, more
preferably from 1 to 5 wt %, based on total application preparation.

[0239] Although each of the aforesaid care-providing substances already
yields a satisfactory result of itself, all embodiments in which the
agent contains multiple care-providing substances, including from
different groups, are also encompassed within the scope of the present
invention.

[0240] The addition of a UV filter allows both the agents themselves and
the treated fibers to be protected from damaging influences of UV
radiation. At least one UV filter is therefore preferably added to the
agent. Suitable UV filters are not subject to any general restrictions in
terms of their structure and their physical properties. Instead, all UV
filters usable in the cosmetics sector, whose absorption maximum lies in
the UVA (315 to 400 nm) UVB (280 to 315 nm), or UVC (<280 nm) regions,
are suitable. UV filters having an absorption maximum in the UVB region,
particularly in the region from approximately 280 to approximately 300
nm, are particularly preferred.

[0244] It has furthermore been found that with structurally similar UV
filters, in the context of the teaching of the present invention the
water-insoluble compound in many cases exhibits the greater effectiveness
as compared with those water-soluble compounds that differ from it by
having one or more additionally ionic groups. In the context of the
invention, those UV filters of which no more than 1 wt %, particularly no
more than 0.1 wt %, dissolves in water at 20° C., are understood
to be "water-insoluble." These compounds should furthermore be soluble at
a proportion of at least 0.1, particularly at least 1 wt %, in common
cosmetic oil components at room temperature. Use of water-insoluble UV
filters can therefore be preferred.

[0245] The UV filters are present usually in quantities from 0.01 to 5 wt
%, based on total application preparation. Quantities from 0.1 to 2.5 wt
% are preferred.

[0246] In a particular embodiment, the agent further contains one or more
substantive dyes. This allows keratinic fibers treated with the agent to
be not only temporarily structured, but also dyed at the same time. This
can be particularly desirable when what is desired is only temporary
coloring (for example, with conspicuous "fashion" colors) which can be
removed from the keratinic fibers simply by washing.

[0256] It is not necessary for the substantive dyes to represent
homogeneous compounds in each case. The agents can instead, depending on
the manufacturing methods for the individual dyes, also contain further
components in subordinate quantities, provided they do not
disadvantageously influence the styling result or do not have to be
excluded for other (e.g., toxicological) reasons.

[0257] Preferably, the agents are free of oxidizing dye precursor
products. Oxidizing dye precursor products are divided into developer
components and coupler components. The developer components form the
actual dyes with one another under the influence of oxidizing agents or
atmospheric oxygen, or by coupling with one or more coupler components.

[0258] Alongside the aforesaid components, the agents can also contain all
active substances, additives, and adjuvants known for corresponding
cosmetic agents.

[0274] With regard to further optional components as well as the
quantities of those components that are used, reference is made expressly
to relevant manuals known to one skilled in the art.

[0275] Agents according to the present invention can be formulated in any
form usual for styling agents, for example, in the form of solutions that
can be applied onto the hair as a lotion or a pump or aerosol spray, or
other preparations suitable for application to the hair.

[0276] Agents according to the present invention are preferably configured
as a pump spray, aerosol spray, pump foam, or aerosol foam.

[0277] For this purpose, the agents are packaged in a delivery apparatus
represented by either a pressurized gas container additionally filled
with a propellant ("aerosol container"), or a non-aerosol container.

[0278] The pressurized gas container with which a product is distributed
through a valve as a result of the internal gas pressure of the container
is referred to as an "aerosol container". A "non-aerosol container" is
defined, conversely to the "aerosol" definition, as a vessel under
standard pressure with which a product is distributed by mechanical
action by a pump system.

[0279] Agents according to the present invention are present preferably as
an aerosol hair foam or aerosol hair spray. The agent therefore
preferably additionally contains at least one propellant.

[0280] Agents that are present in the form of an aerosol product can be
manufactured in usual fashion. Typically, all ingredients of the agent
except for the propellant are introduced into a suitable
pressure-resistant container. The latter is then sealed with a valve.
Lastly, the desired quantity of propellant is introduced using
conventional techniques.

[0281] When in the form of an aerosol spray, propellants suitable
according to the present invention are chosen, for example, from
N2O, dimethyl ether, CO2, air, alkanes having 3 to 5 carbon
atoms such as propane, n-butane, isobutane, n-pentane, and isopentane,
and mixtures thereof. Dimethyl ether, propane, n-butane, isobutane, and
mixtures thereof are preferred. According to a preferred embodiment, the
aforesaid alkanes, mixtures of the aforesaid alkanes, or mixtures of the
aforesaid alkanes with dimethyl ether are used as the only propellant.
The invention also includes the concurrent use of propellants of the
chlorofluorocarbon type, particularly fluorocarbons.

[0282] The propellant is present in agents of the aerosol spray embodiment
preferably in an amount from 30 to 60 wt %, based on total weight of
agent.

[0283] Very preferably, mixtures of propane and butane are used as the
only propellant, at a weight ratio of propane to butane from 20 to 80 to
15 to 85. These mixtures are used in the agents preferably in a quantity
from 30 to 55 wt %, based on total weight of the agent. "Butane" is
understood according to the present invention as n-butane, isobutane, and
mixtures of n-butane and isobutane.

[0284] A particularly preferred aerosol spray of this invention is an
agent, packaged in an aerosol container, containing in a cosmetically
acceptable carrier: [0285] i) 1.0 wt % to 2.8 wt %, preferably from 1.5
wt % to 2.8 wt %, based on total weight of the cosmetic agent, of at

propane and butane at a weight ratio of propane to butane from 20 to 80
to 15 to 85), wherein copolymer (a) and copolymer (b) are present in a
weight ratio range (i) to (ii) from 1 to 1 to 1 to 5, particularly from 1

to (ii) from 1 to 1 to 1 to 5, particularly from 1 to 1.5 to 1 to 2.5.

[0295] For a given spray apparatus, the size of the aerosol droplets and
the respective size distribution can be adjusted by the quantitative
ratio between the propellant and the other constituents of the
preparations.

[0296] The spray rate of sprays according to the present invention is
preferably 6.5 to 10.0 g/10 s.

[0297] Particularly preferred agents according to the present invention
(aerosol sprays) are packaged in an aerosol container having a stem valve
with a stem orifice having a diameter from 0.27 to 0.35 mm. Such valves
are marketed, for example, by the Coster company as model KE or model KEN
valves.

[0298] In addition, nozzles configured as swirl nozzles are particularly
suitable as an aerosol spray for the present invention. Swirl nozzles
comprise a conduit guide, known to one skilled in the art, to the center
inside the nozzle. Swirl nozzles of this kind are marketed, for example,
under the designation "standard micromist insert" by the Coster company.

[0299] A particularly preferred aerosol spray of this invention is an
agent packaged in an aerosol container containing in a cosmetically
acceptable carrier: [0300] i) 1.0 wt % to 2.8 wt %, preferably from 1.5
wt % to 2.8 wt %, based on total weight of the cosmetic agent, of at

orifice with a diameter from 0.27 to 0.35 mm, and preferably additionally
bearing a swirl nozzle.

[0305] A very particularly preferred aerosol spray of this invention is
therefore an agent, packaged in an aerosol container containing in a
cosmetically acceptable carrier: [0306] i) 10. wt % to 2.8 wt %,
preferably from 1.5 wt % to 2.8 wt %, based on total weight of the

[0320] All embodiments of aerosol sprays according to the present
invention preferably possess a spray rate from 6.5 to 10.0 g/10 s.

[0322] Use of the additional preferred ingredients recited above and of
the utilization quantities or utilization quantity ratios identified as
preferred (see above) is also preferred in the context of this/these
embodiment(s).

[0323] In the embodiment as aerosol foam, propellants suitable according
to the present invention include N2O, dimethyl ether, CO2, air,
alkanes having 3 to 5 carbon atoms such as propane, n-butane, isobutane,
n-pentane, and isopentane, and mixtures thereof. According to a preferred
embodiment of aerosol foam, the aforesaid alkanes, mixtures of the
aforesaid alkanes, or mixtures of the aforesaid alkanes with dimethyl
ether are preferably used as the only propellant. The invention also
expressly includes, however, the concurrent use of propellants of the
chlorofluorocarbon type, particularly fluorocarbons.

[0324] For a given spray apparatus, the size of the foam bubbles and the
respective size distribution can be adjusted by the quantitative ratio
between the propellant and the other constituents of the preparations.

[0325] When conventional aerosol containers are used, aerosol foam
products contain the propellant preferably in quantities from 1 to 35 wt
%, based on total product. Quantities from 2 to 30 wt %, particularly
from 3 to 15 wt %, are particularly preferred.

[0326] In order to foam gel-type agents in a two-chamber aerosol
container, isopentane is preferably suitable as a propellant that is
incorporated into the agents and is packaged in the first chamber of the
two-chamber aerosol container. Packaged in the second chamber of the
two-chamber aerosol container is at least one further propellant
different from isopentane that builds up in the two-chamber aerosol
container a higher pressure than the isopentane. The propellants of the
second chamber are preferably selected from N2O, dimethyl ether,
CO2, air, alkanes having 3 or 4 carbon atoms (such as propane,
n-butane, isobutane), and mixtures thereof.

[0327] Use of additional preferred ingredients recited previously, and of
the utilization quantities or utilization ratios identified as preferred
(see above) is preferred in the context of this embodiment as well.

[0328] Agents according to the present invention and products that contain
said agents, particularly aerosol hair sprays and aerosol hair foams, are
notable in particular in that they impart a very natural shine and a
strong hold to the hair that is treated.

[0329] A second subject of the invention is the use of an agent of the
first subject of the invention to generate shine on keratin-containing
fibers, particularly human hair.

[0330] Products according to the present invention containing these
agents, particularly aerosol hair sprays, are notable in that they impart
a very strong, lasting hairstyle hold to treated hair while the hair
remains flexible.

[0331] A third subject of the invention is therefore the use of an agent
of the first subject of the invention for temporary deformation of
keratin-containing fibers, particularly human hair.

[0332] A fourth subject of the invention is a method for treating
keratin-containing fibers, particularly human hair, in which, using a
delivery apparatus, an agent in accordance with the first subject of the
invention is applied as a spray onto the keratin-containing fibers.

[0333] It is preferred according to the present invention that a shape is
imparted to the keratin-containing fibers, and that that shape is fixed
in place by the agent of the first subject of the invention.

[0334] It is further preferred if, after application of the agent
according to the present invention, the agent remains on the
keratin-containing fibers (i.e., is not rinsed out again).

[0335] The delivery apparatuses or aerosol products recited previously are
preferred according to the present invention.

[0336] A fifth subject of the invention is a method for treating
keratin-containing fibers, particularly human hair, in which, using a
delivery apparatus, an agent in accordance with the first subject of the
invention is foamed into a foam and the resulting foam is applied onto
the keratin-containing fibers.

[0337] It is preferred according to the present invention that a shape is
imparted to the keratin-containing fibers, and that that shape is fixed
in place by the agent of the first subject of the invention.

[0338] It is further preferred if, after application of the agent
according to the present invention, the agent according to the present
invention remains on the keratin-containing fibers (i.e., is not rinsed
out again).

[0339] The delivery apparatuses (see above) recited previously are
preferred according to the present invention.

[0340] The examples that follow are intended to explain the subject matter
of the present invention without in any way limiting it.

[0342] The following formulations were prepared by mixing the raw
materials indicated, and decanted into an aerosol can having a Coster
model KE valve and a Coster model V06 "standard micromist insert" swirl
nozzle. The aerosol cans were sealed with the valve, and the
corresponding propellant was then added:

[0343] All resulting aerosol sprays A, B, and C had a spray rate from 0.65
to 1.0 g/s. After application onto the hair, the agents according to the
present invention produced an outstanding, flexible hairstyle hold. The
hair attained a natural gloss.
